I am having trouble getting the City of Dis 100% explored... I have a theory that the 4 or 5 of the rooms that suck you down into the ground might be the cause... as all the room nums I have explored seem sequential... Therefore I am unlikely to be missing any rooms unless they are at either end of the number system...

My question is, does "Above the Swirling Vortex" count towards my exploration before I get sucked into the vortex area, and could that explain why I can't fully explore the area?

Above the Swirling Vortex The mouth of a giganti, swirling mass of dark air twists about itscenter below within an immense fissure of darkness. Streams of dirt androck trail into the vortex as the air rushes over the sides of he nearbyledge, streaking the air with beige and brown colors. The darkness clingsto the sides of the pit like the ink of a giant squid, gripping all thatexists above it.Exits: East Down The shadows surround you, dragging you into the abyss!!The Rumbling Chaos The whipping tail of a funnel rips through the air above the ground,sending debris flying in all directions. Arcs of lightning pierce the skyand thunder strikes the ground with a low rumble. The ground slopessteeply downward, disappearing in the shadows below.Exits: East Down (Brilliant Red Aura) A wicked, four-armed demon scowers the abyss for victims.(Brilliant Red Aura) An ungulated demon with horns tramples through the abyss.(Brilliant Red Aura) A wolf-headed demon guards the entrance to the abyss.

Those rooms shouldn't affect your exploration unless you enter that room right at the point whenthe proc pulses. I did, however, notice one errant room that was approved and put in game as anoversight in that zone. I have since removed that one room from the game as there's nothingthere and you wouldn't be able to reach it anyways without a very lucky teleport spell. Thatroom shouldn't detract from your exploration anymore.

I'll check some further in case there's something unforeseen about those triggers that wedidn't anticipate when they were implemented, however.
